“Abraham ibn Ezra, that restless, versatile Spaniard who wrote on almost every subject which could interest the medieval mind”

“Contemporary with Vitellio and Peccam was… Roger Bacon, a man of almost universal genius, and who wrote on almost every branch of science. He frequently quotes Alhazen on the subject of optics, and seems to have carefully studied his writings, as well as those of other Arabians, which were the fountains of natural knowledge in those days, and which had been introduced into Europe by means of the Moors in Spain. Notwithstanding the pains this great man took with the subject of opticks, it does not appear that, with respect to theory, he made any considerable advance upon what Alhazen had done before him.”

“As a mother, I've always thought of September as a special month, a time when we bundled our children off to school, to the warmth of an environment in which they could fulfill the promise and hope in those restless minds.”

“Adams could no more interest Algernon Swinburne than he could interest Encke's comet. To Swinburne he could be no more than a worm. The quality of genius was an education almost ultimate, for one touched there the limits of the human mind on that side; but one could only receive; one had nothing to give — nothing even to offer.”

“A ruffled mind makes a restless pillow.”

“(…) there is no such thing as peace of mind. Mind means disturbance; restlessness itself is mind.(…) Examine closely and you will see that the mind is seething with thoughts. It may occasionally go blank, but it does it for a time and reverts to its usual restlessness. (…).”

“A restless state of mind that wanders away from an object while observing it is a mental state called restlessness (uddhacca). It flies away from the object. Due to restlessness the mind cannot remain very long with an object but often wanders elsewhere.”

“For love of bustle is not industry – it is only the restlessness of a hunted mind.”
Nam illa tumultu gaudens non est industria sed exagitatae mentis concursatio.

“The bond price, and, as an arithmetical and rigid consequence, the interest rate is an inherently restless variable.”

“What I dream of is an art of balance, of purity and serenity, devoid of troubling or disturbing subject matter, an art which could be for every mental worker, for the businessman was well as the man of letters, for example, a soothing, calming influence on the mind, something like a good armchair which provides relaxation from physical fatigue.”
